JOHN R. LEONARD ATTORNEY United States Patent Ofiice 3,281,997 Patented Nov. 1, 1966 3,281,997 CHIMNEY-SIMULATHVE ROOF EMBELLISHMENTS John R. Leonard, 12164 Criterion, St. Louis County, Mo. Filed Dec. 10, 1962, Ser. No. 243,437 12 Claims. (13!. 52-57) This invention relates in general to certain new and useful improvements in architectural embellishments for residential roofs and, more particularly, to a prefabricated simulated chimney provided for attachment to a roof.

Due to the high cost of labor and structural materials, masonry chimneys and masonry flues have become unduly expensive for residential construction. Moreover, in lowcost residential construction the extensive use of gas-fired furnaces and gas hot water heaters has made it possible to employ relatively inexpensive metal stacks or flue pipes which project only a few feet above the roof. It has, therefore, become a common practice in the building industry to dispense with conventional masonry chimneys and utilize instead a heavy metal flue pipe.

These metal flue pipes or'stacks are usually unsightly and the absence of a conventional masonry chimney immediately lowers the value and appearance of the building. Some efforts have been made in the past to overcome this problem by providing chimney housings which can be mounted upon or around the flue .pipe and disguise it. The chimney housings heretofore developed, however, have been very costly and diflicult to install. One rather serious disadvantage of such structures resides in the fact that they must necessarily be attached to the roof with some type of fastener and this inevitably causes roof leaks.

A second rather serious disadvantage of such structures resides in the fact that they normally impede the natural air draft which carries away the smoke from the stack. Moreover, such chimney housings are accumulators of rain water and during rainy seasons allow a pocket of water to build up arund the stack and overflow into it with resultant damage to the furnace and hot water heater.

Another problem which has been encountered in the use of chimney housings results from the fact that residential roofs do not have any standard pitch. The pitch of residential roofs will vary from a very shallow angle of ten degrees to a very steep angle of forty-five degrees or more. In fact, this is a matter of individual taste and depends largely upon the architectural styling which has been selected. Consequently, each chimney housing must be designed especially for the house on which it is to be installed or the chimney housing must be fabricated with rather elaborate built-in geometrical guidelines to accommodate encountered range of roof-pitches. Either expedient is quite costly and to a very large extent destroys any economy which would be achieved by eliminating a genuine masonry chimney.

It is, therefore, the primary object of the present invention to provide a simulated chimney which can be attached to a roof or similar supporting structure with a minimum amount of effort and which does not require skilled labor or specialized installation tools.

It is another object of the present invention to provide a simulated chimney of the type stated which is relatively simple and economical to manufacture.

It is an additional object of the present invention to provide a simulated chimney of the type stated which will not impede the normal lair flow across the chimney flue, and yet will effectively screen unsightly flue pipes or metal stacks from public view.

It is also an object of the present invention to provide a simulated chimney of 'the type stated which is constructed in such manner that it is capable of being attached to a roof or similar structure by the home-owner without resort to skilled labor.

Referring now in more detail and by reference characters to the drawings, A designates a simulated chimney which comprises a pre-formed solid rectangular block 1 formed of a non-burning polyurethane foam, flame resistant polystyrene foam or other similar rigid but lightweight material, having a front face 2, a back face 3, a pair of transverse side faces 4, 5, a top face 6, and a bottom face 7. Rigidly secured to the front face 2 adjacent its lower margin, and extending transversely thereacross, is a flange or bracket 8 which is integrally provided along its lower longitudinal margin with a hinge-forming tube 9 which is sized to accommodate a pintle rod 10. By reference to FIGS. 1 and 2, it can be seen that the pintle rod 10 extends outwardly beyond the side faces 4, 5, for a short distance and is maintained in close proximity to the adjoining margins of the front face 2, and the bottom face 7.

Swingably mounted on one of the extended ends of the pintle rod 10 is an angle-guide 11 of L-shaped crosssection and integrally including a normally vertical flange 12 which is integrally joined along its longitudinal margin to a laterally projecting flange 13. Similarly mounted on the other projecting end of the pintle rod 10 is a matching angle-guide 14 of L-shaped cross-section and having a normally vertical flange 15 which is integrally joined along its longitudinal margin to a laterally projecting flange 16. The angle-guides 11, 14, are hinged from the pintle rod 10 in such a manner that the lines between the axis of thepintle rod 10 and the centers of gravity of the angle-guides 11, 14, are parallel to the planes of the underfaces of the projecting flanges 13, 16, so that, when the angle-guides 11, 14, hang down under the influence of gravity, these planes will be in true vertical position. The projecting flanges 13, 16, are provided with the lines of spaced apertures 17 and the normally vertical flanges 12, 15, are each provided with a single aperture 18 located adjacent the outer or freeswinging end thereof.

The simulated chimney A can be very simply fitted to a pitched roof as shown in FIG. 4 by laying the simulated chimney A down upon its back face 3 along the surface of the roof in front of the projecting flue pipe or stack s, as shown in FIG. 3. In this position, the angle-guides 11, 14, will swing freely down into vertical position under the'influence of gravity and hang in this position so that the flat faces of the projecting flanges 13, 16, will define a plane which is accurately located at an angle x with respect to the bottom face 7. It will be evident, as a matter of simple geometry, that this angle x is precisely equal to the angle y between the surface of the roof R and the true horizontal. The angleguides are then fastened in position by inserting pins 19 through the apertures 18.

Thereupon, the base portion of the block 1 is suitably out along this plane as established by the flanges 13, 16, so that, when set in upright position upon the roof R, it will appear in a truly vertical position, as shown in FIG. 4. Since the block 1 is made of foamed synthetic resin it is easily cut with a knife or carpenters saw. In this connection, it should be noted that the angle-guides 11, 14, are slightly shorter than the transverse dimension of the block 1, that is to say, they are shorter than the width of the side walls 4, 5, so that they never project beyond the front face 2. When the block 1 is cut or beveled, as above described, the underside thereof is coated with a thick viscous film of catalyzed epoxy resin adhesive and, similarly, the upper surface of the roof R is coated in the area in which the simulated chimney A is to be attached. Epoxy resin adhesives are conventional and, therefore, not described in detail herein. The block 1 is then set into the body of adhesive applied to the roof and gently shifted around to settle it firmly as well as to line it up square with the building. In addition, it can be adjusted with a level to assure precise vertical alignment. Upon setting, the resinous film will set to form a hard permanent bond in which the simulated chimney A is permanently secured to the roof R in the manner as shown in FIGS. 5 and 6. The underside of the horizontal plate 14 is also coated with the epoxy resin adhesive to aid in aflixing the block 1 to the roof R, and as the simulated chimney A is squeezed down into place the adhesive will flow upwardly through the apertures 17 increasing the holding power of the adhesive bond. It can be seen that the stack s is always hidden from view from the front side or the rearward side of the building by the simulated chimney A and by the peak of the roof R. In other words, if the stack s were projecting from the roof R on the forward side of the building, the simulated chimney A would be affixed to the roof R in a position in front of the stack s. The simulated chimney A would then hide the stack s from view on the forward side of the building and the ridge of the roof R would hide the stack s from the rearward side of the building. By this mode of construction, the simulated chimney A does not interfere with the normal air-flow and draft across the stack s. Of course, the stack s is not entirely hidden from view when the structure having the roof R is approached from the side. However, the simulated chimney A is much more predominant than the stack s and will immediately attract the attention of the viewers.

The polyurethane foam block 1 is preferably surface-contoured and formed with a colored pigment to simulate the natural brick. Moreover, the block 1 may be painted on its exterior surface with a series of white stripes to represent the mortar lines and, thus, giving the outer appearance of a masonry chimney. It should be noted that if the roof R is made of shingles, the epoxy resin adhesive may also be applied to the underside of the overhanging margins or flaps of any shingles on the roof R in the area to which the simulated chimney A is fastentd and thereby secure each shingle to the next underlying shingle so that wind pressure against the sides of the simulated chimney A will not peel the shingles up away from the roof R.

It is possible to provide a modified form of simulated chimney B, substantially as shown in FIGS. 7-12, which is adapted for mounting straddlewise across the ridge of a roof R and comprises a solid rectangular block 20 also formed of a polyurethane or polystyrene foam, as is the simulated chimney A. The simulated chimney B comprises a front face 21, a back face 22, a pair of transverse side faces 23, 24, a top face 25, and a bottom face 26.

Rigidly mounted within the block 20 and projecting at its opposite end outwardly from the transverse side faces 23, 24, is a hinge rod 27 which is so located that it is equidistant from the front face 21 and the rear face 22. Swingably mounted on opposite projecting ends of the hinge rod 27 are pairs of opposed angle-guides 28, 29, which are substantially identical to the previously described angle-guides 11, 14, and have a length which is slightly less than half the transverse dimension of the block 20. The angle-guides 28, 29, integrally include normally vertical flanges 30, 30, and laterally projecting flanges 31, 31, the latter having lines of spaced aligned apertures 32, 32'. The adjacent ends of the flanges 30, 30', are chamfered in the manner as shown in FIG. 7 so that they will not interfere with each other when the angle-guides 28, 29, are in final position. Finally, the flanges 30, 30', are provided with apertures 33, 33', respectively, which correspond to the apertures 18 of the previously described simulated chimney A. Swingably mounted on the opposite transverse end of the hinge rod 27 is a pair of guide supports 34, 35, which are substantially identical to the guide supports 28, 29, and are respectively provided with pairs of normally vertical flanges 36, 36', and laterally projecting flanges 37, 37', the latter preferably having lines of apertures 32, 32, respectively, which are identical in type, location, and function to the apertures 32, 32', of the flanges 31, 31' The normally vertical flanges 36, 36', are similarly provided with apertures 39, 39', which also correspond to the previously described apertures 18. It should also be noted that the hinge rod 27 is sufliciently spaced from the bottom face 26 so that a notch having any needed depth or angle can be cut in the end of the block 20.

The block 20 is also colored with a pigment which simulates the color of brick, and is pointed or indented V on its exterior surface with lines simulating mortar joints.

The bottom face 26 may be cut with a V-shaped notch so as to conform to the ridge of the roof R in the manner shown in FIG. 11, very much in the manner previously described. In order to determine the lines of cut, the block 20 is positioned on the roof R so that its top face 25 is presented upwardly toward the ridge of the roof R and its front face 21 lies in flushwise engagement upon the upper surface of the roof R. In this position, the angle-guides 28,34, will hang downwardly in a true vertical position and, in effect, act as plumb-bobs. In this position, tacks or pins 19' similar to the pins 19 are inserted through the apertures 33, 39, thereby rigidly securing the angle-guides 28 to the transverse faces 23, 24, of the block 20. It is to be noted that the opposite angle-guides 29 are swung upwardly out of the way. After the angle-guides 28 are secured, the block 20 is moved to the other side of the roof R or to the position as shown in FIG. 10, also with top face 25 spaced a short distance downwardly away from the ridge of the roof R. In this position, however, the rear face 22 will lie flushwise engagement upon the upper surface of the roof R, and the angle-guides 29 will hang downwardly in a vertical position. Thereupon, tacks or pins 19 similar to the pins 19 are inserted through the apertures 33', 39', for rigidly securing the angle-guides 29 to the rigidly secured, projecting flanges 31, 31', thereof form guide lines from which a V-shaped notch can be cut. The angle of cut is obviously equal to the angle of the ridge or peak of the roof R. Consequently, the simulated chimney B will precisely fit upon the roof R in the manman as show-n in FIG. 11. -It will be noted, for example, that the guide member 23 is attached to that inclined portion of the roof which formed the support for the chimney while the guide member 28 was being secured thereto by the pins 19.

It is also possible to provide another modified form of simulated chimney C substantially as shown in FIGS. l3l6, which comprises a solid rectangular block 40 also formed of a polyurethane or polystyrene foam as is the simulated chimney A, and preferably though not necessarily, being molded on its exterior surface to simulate brick work or masonry. The simulated chimney C comprises a front face 41, a back face 42, a pair of transverse side faces 43, 44-, a top face 45, and a bottom face 46. This bottom face 46 may be located at some pre-selected angle with reference to the front face 41 and back face 42, so that the user will not have to bother with cutting or fitting the simulated chimney C. This is commercially feasible for many local ities, inasmuch as builders in large metropolitan areas, either for reasons of architectural conformity or compliance with some established building code, will utilize some uniform pitch angle for the roof in the dwellings being constructed. Analysis of residential building specifications in many large metropolitan areas of the country has indicated that in some areas only a few different roofpitch angles are commonly employed. Consequently, simulated chimneys such as the simulated chimney C can be supplied in several different sizes and roof-pitch angles without encountering severe inventory problems.

In order to mount the simulated chimney C upon a suitable roof structure R", the bottom face 46 in the appropriate area of the roof structure R" is coated with an epoxy resin adhesive of the type previously described. When the adhesive coating has set sufficiently so as to have acquired the right degree of tackiness, the simulated chimney C is set into place and gently shifted around to settle it firmly as well as to line it up squarely with the building. By utilizing a sufficiently heavy layer of ad hesive, it is possible to set the simulated chimney C lightly in place and then squeeze it to one side or the other as circumstances may require, using a carpenters level to achieve substantially accurate verticality and alignment.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the chimney-simulative roof embellishments, may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

The method of preparing and afiixing a simulated chimney to a roof having first and second planar roof surfaces which intersect in the formation of a ridge, said simulated chimney having first and second spaced parallel side faces perpendicularly intersected by front and. back faces and gravity responsive guide-members swingably mounted in overlying relation to the side faces for estab lishing vertical planes therethrough, said method comprising supporting said chimney on said roof with its front face in facewise abutment with the first roof section and so that its upper end points upwardly toward the ridge of the roof causing said first guide-members to freely swing to the true vertical position thereby establishing a first plane through said chimney, reversing the position of the chimney so that the back face lies in facewise engagement with the second roof surface and its upper end points towards the ridge of the roof causing the second guide-members to freely swing to a true vertical position thereby establishing a second plane through said chimney which intersects said first plane in the formation of a dihedral angle, rigidly securing said guide-members to the side faces of said chimney when in said last-named positions, severing the base of said chimney along the first and second planes thereby forming .a V-shaped bottom surface, setting said chimney on the roof in an upright position with the vertex of the dihedral angle in juxtaposition to the roof ridge and the V-shaped bottom surface in facewise engagement with the first roof surface, and rigidly securing said chimney to said roof in said last-named position.
